i am going to have the following parts

cooler master haf x case
asrock x79 extreme 7 mobo
intel i7 3930k cpu
cooler master hyper 212 evo cpuy cooler
g skills ripjaws x series 16g ram
amd radeon hd 7990 v-card
rosewill lightning-1300 psu
sata 2tb hard drive
sony 24x optical drive
120g ssd

was thinking about when i need to upgrade i could add more 7990's and was wondering how many of them the rosewill could handle

More about : 7990 hold

Well, considering there is absolutely zero information about the 7990 out it would be impossible to tell, exactly.

That said, you only can do up to quad crossfire, which would be two 7990s.

So unless you want to run 4x 7990s with two of them NOT crossfired, the max would be 2. Presumably a 1300W PSU could handle that, even if it is a Rosewill.

Buy a $1,250 PC ...

and a really nice $1,750 HD projector.

If you weren't so cheap, you could buy one of these

My point, I guess, is at 5760x1080 I suspect your frames will be roughly one-third of that at 1920x1080 with a single Radeon HD7990 (which, honestly, could be matched in viewing pleasure with a few modded HD6950's at 15-20% less in cost).

And instead of being stuck with 3 monitors at less than 4' by 2' (and dealing with the bezels, setup, general pain and complexity ...), you will only be limited by the size of your blank wall.

Find yah a 7.1 receiver and some cheap speakers (these go on sale for $150 from time-to-time!), a nice wireless KB/M ...

and if we knew where you lived, we'd come over and beat you up!!

i love these posts where people ask for details and advice on the specifics of unreleased technology.

btw how many 8990's will my system hold? im wanting to run 6
and im building a BF4 pc, what mobo should i get for the CPU i want? the new, unreleased, unannounced, unconfirmed I9 8core 16 thread 8.4ghz LGA L337 socket?

dont be sorry be smart.

if you come in here asking about top of the line tech with questions like wanting to run more than 2 7990's (or 6990's) it means one of a few things.

A. Someone with pipe dreams of a kick ass PC who comes to forums to try to look cool (e.g. im getting something all of you want, na na na!)

B. Your a kid with dad's money and no clue.

putting items in your signature like you own them before they are released makes me thing ur a little of both.

google is a powerfull tool. a little bit of research will go a long way, save you time and wont leave everyone thinking "what a tool"

i was just wondering cuz eventually 7990's will be obsolete and wanted to see how many i could put on it without upgrading wont even get the second one for 1 or 2 years and i put it on my sig cuz lot of ppl do that and ive been researching on this pc 4 2 months and if i haad the money id buy it NOW but i have to save up for at least half another year and i THOUGHT that this forum was MADE for asking questions jeez man i was just planning ahead

so your still 6 months off buying anything?

good chance you will never get the i7 3930k as IB will be out and who says the nvidia GTX6xx wont drive the 7xxx into the ground?

you can only run 2x (TWO) Dual GPU cards, be it AMD or Nvidia giving a total of 4 GPU's over 2 cards.

6 months is way to far to be planning this down to every nut and bolt.
just read articles and reviews until its >1 month to go. then look at some ball park pricing on what tech is avaliable. post your questions (if you have any after 6 months of reading reviews and benchmarks)

By the time 7990's are actually obsolete to the point where you wouldn't be looking at near max settings on nearly any game with them anyways that core I7 will be looking far worse than those.

By the time you want a new 7990 because it's obsolete, they won't be on the market... like trying to find a 5970 now.

Also, you need to save another half a year to build an over-the-top PC? Why not buy something worth a LOT more bang for your buck. Like an i5 2500k or maybe an i7 2600k (or 2700k if you want)? Saves several hundred right there.

Also maybe three 7950s would kick serious ass at 5760x1080 in 3D, three 7970s if you can afford it. Dual GPU cards are always more expensive, hotter, and slower than two single GPU cards.

As for signatures, people put the hardware they own in them. Not the hardware they dream about. Usually.

The point is, save how ever much money you are willing to drop on your pc, once you have the money you plan to spend, then research and question. Even though the 7990 won't be released for a while, prior dual gpu cards don't perform as well:
2x 7970 > 7990
2x 6970 > 6990
2x 5870 > 5970
two individual cards won't run into as many heat issues and won't have to try to meet pcie standards (not that there aren't cards that break the standard)

don’t need to advertise to everyone your saving for a PC. Specially how you’re quite far off still.

pple will start to realise your > 15 y/o.

I could say I’m saving for dual 7970's or an SB/IB upgrade but I’m just saving $$$, I’ll spend it on whatever tech is worth it at the time I’m ready to buy.

About the only thing you could count on buying now or in 6 months and it make no real difference is the case & PSU

asking about the other items is redundant as there is a fair chance you will choose other items when it comes time to buy.

omega21xx is correct.

however the reason pple will choose the dual GPU cards is i believe you can only run 3x cards on current intel chipsets. and the 2x 7990 > 3x 7970 same goes for the 6xxx series. (even tho its a minimal performance upgrade, when your talking the top of the charts people will pay 90% more for 10% gain.

personally i would go with the seperate cards rather than dual GPU card/s

The only purpose i see for dual gpu cards (not that you are wrong, you're completely correct) is if you have only 1 pcie x16 slot and want the best your board can do, that's the only time I'd consider a dual gpu card as an option. Otherwise it has very diminishing returns.

Why is your grammar so bad? It is very hard to read what you type and the 7990 is not going to perform as well as 2 7970's. By that time Nvidia's Kepler gpu's will be out and you are going to want the Gtx 680 which outperforms the 7970.

6 months is still a long time out.

How much will the 7990 be? what price will the 7970 be after the 7990's release?
what is the performance diff between 2x 7970 vs 7990?

what will the GTX680 perform like and at what price point?
will 2x GTX680 > GTX690.

you just cant make decisions now for a purchase 6 months away without knowing more info that is not yet avaliable.

ask the question after the 7990 & the GTX6xx is actually released. then atleast you will be able to compare the items rather than speculation on future products based on past events & trends.

I shall give you an estimation which won't be too far off, it will run about 90-95% of the speed of cfx 7970. Now you may get it to perform 99% of the speed of the cfx 7970 if you speed it up to 7970 clocks on both gpu's and memory. But you won't reach the performance of a OC'd pair of 7970's.
Heat will interfere too much to allow you much past stock cfx 7970.

/sigh @amuffin your another person making assumptions on unreleased tech based on marketing from vendors.

Nvidia's PR machine is working overtime to Hype up the release of the GTX6xx

Let me see some REAL WORLD benchmarks with cards avaliable to the public before starting to rant and rave about this not yet released card is faster than that not yet released card.

we all know benchmarks can be bias towards either ATI/AMD or Nvidia. lets see a broad range of test and compare the results like grown ups.

@omega21xx yes based on previous dual gpu cards i agree.

6990 ~ 2x 6950
5970 ~ 2x 5850

and im sure the 7990 will sit somewhere near 2x 7950's

2xGPU scaling = "living the high life of near-double frames"

The third GPU begins a serious point of diminishing return - maybe a 25% boost at best ??

With the forth GPU in the mix, you ain't getting much of anything, and may well be backin' up due to configuration issues.

CF wont support more then 4x so only 2 7990 for you and well the i7 is realy a waste if your not using hypertrading a lot since it won't beat an i5-2500k. For gaming the i7 will perform worst "period" (only a few FPS loss). Well the 2600k beated a 2500k by like 3fps on some massively overclocked eyefinity set-up on BF3 multiplayer because the multiplayer part can be ran on different core then the game itself.

But for the 100$ it doesnt even worth mentioning it and for the price of an i7-3930k compare to an i5-2500k you just don't want to do it for a gaming PC.

Actualy your wrong 2x single GPU < dual GPU. Far less microstuttering on dual GPU then on using two GPU.

yes if you look at the spec of a dual GPU you might think its worst then going for two single GPU but actualy it isn't. Also configuring 2 card in CF can be a nightmare sometimes and you need to use 2 of the same brand.

a 7990 will cost far less then 2x 7970, will be more stable and use a little less power. As for the heat problem if you can affort a 1000$ GPU you should be able to afford the cooling needed to run such a beast.

I'm just going to ignore your post as you are uninformed based on this line "you need to use 2 of the same brand"

Microstutter is still a very real problem for a dual gpu card.

This is actually 2 questions.

1) Is an i7 2600k powerful enough to not limit framerates below an acceptable threshold? This question is applicable no matter what GPU you want to use, even a 5770. The answer is that currently in every single game a 2600k will have the ability to put out hundreds of frames per second with only a few exceptions. Essentially, put any game at 1024x768 at low settings and see what your max framerate is. Increasing visual quality affects the GPU not the CPU.

2) Are my GPUs going to be powerful enough for acceptable gaming frame rates? This question is entirely dependant on the setup. Higher resolutions and settings obviously require more powerful GPUs. As long as question 1 is answered with a yes, you could add as many of the fastest GPUs possible and either get or not get a bottleneck, depending on what game and settings you are at.

The more concrete answer is that no, an i7 2600k is not going to bottleneck anything.

My point is (whether or not its due to game support, drivers, or CPU bottlenecking) 3 or 4 will almost never grant 3 or 4 times performance. Using more than 2 you'd need about a 4.5 ghz to drive 3 well.

Well, fair enough, except that the 7970s actually scale exceedingly well. Like, up to 100% kind of well.

http://www.hardwareheaven.com/reviews/1376/pg1/sapphire...

http://tpucdn.com/reviews/ASUS/HD_7970_CrossFire/images...




In the first link they got nearly linear scaling from 1 to 2 to 3 cards, with only 4 cards dropping off the scaling noticeably. That's pretty friggin good!

I do agree that more than 2 cards is a little bit of a waste, although I think maybe that number will be 3 from now on - 3 has the benefit of less stuttering as well.

Thanks for the links :)  hadn't seen those yet. Good to see the 7970 doing well in shogun which cripples most cards when going above 1080p
If I remember correctly I saw some benchmarks for 2x 6990 vs trifire 6970. If i remember correctly the 6970's were usually the same or better, but I might be wrong. They were close is all I know for sure :lol:

wow is this thread still going?

let it die already. start it back up in 5 & 1/2 months when he is ready to buy and this is not all just a pipe dream.

the moral of this story is.....dont bother looking at which CPU, Mobo, Vid Cards, RAM or HDD you "THINK" you "MIGHT" get if you had the money now. because the simple face is you dont. and wont for a while. hardware WILL change and some big changes at that (IVY Bridge & GTX 6xxx).
